Free-flow tolling in France: how it works in 2026

Free-flow tolling is transforming the French motorway experience. No more queuing at toll barriers: gantries with cameras scan licence plates on the fly without you slowing down. First tested on the A79 between Montmarault and Digoin, the technology was extended in 2024 to the A13 and A14 between Normandy and the Paris region, then to other sections in 2025. Convenient but tricky, the system requires quick payment to avoid steep fines.

How free-flow tolling works

Automatic reading and network of gantries

Concretely, when you drive under a gantry, high-resolution cameras capture your front and rear plates. Data is sent to a central system that calculates the amount due based on the sections used. If you have an electronic tag, payment is automatic as before and you have nothing to do. Without a tag, you must pay yourself on a dedicated website or at a partner tobacco shop. The A13 and A14 use sanef.com/flux-libre while other concessionaires (APRR, Vinci) have separate portals.

Why this system was adopted

Free-flow smoothes traffic, removes emissions from acceleration and deceleration at toll plazas, and lowers maintenance costs. Road safety authorities also report a drop in rear-end crashes around removed toll plazas. For concessionaires, the return comes from removing booth staff and improving pricing accuracy.

How to pay after your trip

The 72-hour window and accepted channels

You have 72 hours after passing under the last gantry to pay the toll. Payment is made online by entering your plate, no mandatory account creation. You can also visit a tobacco shop displaying the Nirio logo, or pay by card at a dedicated terminal on certain service areas. The amount is exactly what you would have paid at a classic toll, with no extra fee if paid in time.

If you forget: notice, then fine

Beyond 72 hours, the concessionaire sends a payment notice with a 10-euro surcharge, payable within 60 days. If you still do not react, the case is forwarded to the public Treasury and you receive a fixed fine of 90 euros. Without payment, the fine can grow to 375 euros. Golden rule: pay the same day on the site, or subscribe to a tag to remove the risk.

The electronic tag, your essential ally

Fees, caps and subscriptions

The tag generally costs 1.70 to 2 euros per month of use, sometimes with free months when you do not drive. It also works in Spain, Italy and Portugal depending on the issuer. Main providers are Bip&Go, Ulys (Vinci), Fulli (Sanef) and Liber-T (APRR). In 2026, several operators offer a connected tag that notifies you instantly of each gantry passage and the deducted amount, handy for expense reports. The tag is required to access subscriber discounts (up to 30% on the A14).

Plans for heavy users

For those using the A13 or A14 more than eight times a month, monthly unlimited plans exist between 80 and 110 euros depending on the origin. The plan pays off from the ninth round-trip. Fleets can centralise all tags of a company on a single account with a single electronic invoice.

Future deployments and signage

A33 and other announced sections

After A79, A13 and A14, several other motorways will switch to free-flow. The A33 between Nancy and Luneville is planned for 2026, the Alsatian A35 is under review, and sections of A86 and A4 are being studied. By 2030, half of the French motorway network could operate without any barrier. This brings new signage: orange panels specific to gantries, road marking, and alerts announcing the absence of a toll plaza.

Tips for foreign drivers and rental cars

If you drive a rental car, the agency is billed automatically through the contract and passes on the cost with sometimes 25 to 35 euros of handling fees. For foreign-registered vehicles, European agreements let the concessionaire find the owner and send a postal invoice. The 72-hour window applies too, so anticipate via the international site if you do not own a tag.

Practical recap

Reflexes to avoid being fined

Write down the date and motorway when you get out of the car. Pay the same evening on the concessionaire's site, or plan a tag purchase if you use the network more than once a year. Keep the payment receipt for at least six months. If you change plates (sale, rental), update the tag contract. In case of dispute (panel not visible, broken gantry), keep photos and witnesses: the litigation service is generally responsive when the file is solid.

DevisPermis expert opinion

Free-flow is great news for driving comfort but bad for the distracted. Most drivers who get fined are occasional users who did not see a gantry or thought their partner's tag had paid. Our advice: if you use the A13 or A14 more than twice a year, get a tag. Real cost is under 25 euros per year if you do not drive every month and it will be quickly recovered by the first fine avoided. Watch out for fraudulent SMS imitating the official site: never pay through a link, always go directly to the concessionaire's website. Remember that free-flow does not remove tolls, it merely shifts them in time.
